He tried to change the image of the fallen angel bloodline that was negatively imprinted on him. So he participated in the war at a young age. He won. He made a name for himself not only in the Heaven but also in the world of demons and fallen angels, proving that he was strong. And he was recognized by all the angels, to the point that he received the title of El, which only the highest-ranking angels receive. That's why he became one of the ten El angels, and he thought everything had changed. He thought that even if you had the blood of a fallen angel, if your heart was pure, you could rise to a high position in the Heaven and be recognized.... 
He was definitely recognized. But....
The high-ranking angels in Heaven couldn't stand seeing someone with impure blood reach their level. So they set him up, framing him for treason. Now the same angels who once fought alongside him are hunting him down.
With no safe place left in Heaven and certain death if he stays, he's given one last option: escape to the human world. There, he must give up his identity as a legendary warrior and live as an ordinary human named Issei.

Note: At the beginning, he uses only his human abilities, not his archangel powers or Ddraig’s full power. There are multiple reasons for this. Please read before saying he’s weak or not that powerful.
